This is just my opinion
RA is a VERY short man. Only 5% of adult males are 5’4 or shorter, that would be what someone notices about Richard Allen if there was a brief interaction: “that was a short man”. It would stand out much more than his clothing or his mood “he didn’t seem very happy” before any of that it would be “short man”
It seems as if out of the 4 witnesses so far, nobody has described a short man. Instead they have all been pretty close to putting the man around 5’10… half a foot taller than 5’4…. The same difference between someone who is 5’8 and 6’2 to put it in perspective.
RA does not = BG for this reason alone.
